Introducing the ultimate evolution in spark plug technology and performance.
Iridium Spark Plug Iridium, with a higher melting point and higher resilience to oxidation than platinum, offers a dramatic increase in durability and service life.
Unique two-stepped center electrode with a secondary micro-discharge burns off carbon deposits as they form.
Taper cut ground electrode ensures an excellent flame spread and improved vibration resistance.
A super fine center electrode—just 0.6mm—for increased power, acceleration, fuel efficiency and ignitabillity.
Iridium – Superior to Platinum
